I remember when the Titanic sank in 1912, it was the ship that was supposed to be unsinkable. The only thing it ever did was sink. When it took off from England, all kinds of passengers were aboard - millionaires, celebrities, people of moderate means, and poor folks down in the steerage. But a few hours later when they put the list in the Cunard office in New York, it carried only two categories - lost and saved. Grim tragedy had leveled all distinctions.
